Final answer:
The final pressure of the gas when the volume is increased to 760 cm³ while maintaining a constant temperature is approximately 124.9 kPa, according to Boyle's Law.
Step-by-step explanation:
The question involves applying Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume when temperature is held constant. Given the initial volume of 450 cm3 with a pressure of 211 kPa, and the final volume of 760 cm3, we can find the final pressure using Boyle's Law:
P1 * V1 = P2 * V2
(211 kPa) * (450 cm3) = P2 * (760 cm3)
P2 = (211 kPa * 450 cm3) / (760 cm3)
P2 ≈ 124.9 kPa
The pressure when the volume is increased to 760 cm3 is approximately 124.9 kPa, rounded to one digit past the decimal.
